【グッチ】ギルティブラックプールオム 90ML EDT(並行輸入品)

Q: How long does the scent last?

I dont know the same as any other scent. Ive never actually timed it or any other cologne now that I think about it. Sorry

Q: Is this cologne authentic & sealed?

It was sealed n I purchased directly from amazon

Q: How do you know if this is authentic Gucci guilty black cologne? I hear that most of the clothes sold or not authentic

I bought the regular Gucci Guilty from Macy's and it was amazing, lasts long. When I decided to order from Amazon, I'd figured I'd try the dark version. The fragrance was stronger but didn't last as long as the one I bought from a department store. It depends on the person I guess, hope this helps!
